Rotating Joint Origins Bug

[Anonymous]

When you are creating a joint origin, is there a way to rotate the joint on other axes (apart from the one normal to the face it is on). I want the joint origin on the cylindrical body to be rotated by 90 degrees around the Y or X axes (the Y axis is currently pointing up in this screenshot). Basically, if the joint origin were an infinite plane, I would want it to cut the cylindrical piece in half to obtain two semi-circle cylinders. Is there an easy way to do this? No rotation options for that axis show up. A Fusion arachive file is also attached.

Hi Alexander,

The fact there is only 1 rotation axis shown is the current behavior for the joint origin command.  If you need to create a joint origin at this specific location that would cut the cylindrical piece in half, you can use construction geometry and create it in the component with the body.  

For my understanding if you were able to create the joint origin the way you want, what would you be looking to do next?  If I better understand what you are looking to accomplish I might be able to offer another solution.

Joel,

Thanks. Basically, what I want to do is constrain the two cylindrical pieces along an axis parallel to the X axis. So I would like their flat faces to lie on the same plane as they do now, and only allow the parts to translate along the axis normal to the joint origin face. Does that make sense?

I guess, my bigger thought is: currently, the joint origin tool only allows for a little bit more customization of joints than just the joint tool. The only customization available is to translate the joint origin from a selected point, and rotate around one axis, which is normal to the joint, so the joint origin tool has a very limited translation/rotation selection feature. Is there a reason why the other rotation behaviors are not in place?

Hi Alexander,

It sounds like the planar joint might work for what you are looking to do.  Maybe I am not understanding exactly what you are looking to do.

On another note, I have created a video that shows with your model how to create the joint origin in a way that may work for you, though it does take a little tweaking.  The great thing about joint origin is that you can use other geometry or work planes to help reorient the origin.

Cheers,
